Recovers (1) a file that contains bad sectors, or (2) all files on a
disk that contains bad sectors in its directory.
Parameters
pathname specifies the file to recover.
drive: specifies the disk to recover.
Notes and Suggestions
• If you perform the RECOVER procedure on an entire disk, it
changes all filenames to the format,
filennnn.rec,
where
nnnn
is a four digit number unique to each file.
• In recovering files that contain bad sectors, MS-DOS reads the
file sector by sector.
It
marks the bad sectors in a system
table so that the data is never again allocated to them.
• In recovering disks that contain bad sectors, MS-DOS scans
the disk File Allocation Table (FAT) for chains of allocation
units. It creates a new root directory for each chain. Use the
RECOVER drive: command only if the disk's directory is
unusable.
• If there is not enough room in the root directory, RECOVER
displays a message to this effect. It then stores information
about the extra files in the File Allocation Table. When there
is enough room, you can use RECOVER again to regain the
files.
• If you have trouble storing and manipulating information, the
disk may have a flawed sector. Running CHKDSK (check
disk) should indicate whether this is the case. If the file that
contains the flawed sector is a text file, recover the file. This
saves all information except that in the flawed sector. Reenter
the lost information. If the file is a data file, recovering the
file mayor may not help.
• If you are a beginner, you may prefer reentering all informa-
tion rather than trying to recover a file.
